Description

CamClay micropolar and micromorphic dataset Created by Zeyu Xiong, zx2312@columbia.edu on Aug 1, 2023 The dataset consists of the elastoplastic micropolar/micromorphic stress vs. deformation data. There are 5 folders containing perfect plastic and hardening data. CamClay_mpol_init1: perfect plastic data of Cauchy deformation. CamClay_mpol_init2: perfect plastic data of micropolar deformation. CamClay_mpol_init3: perfect plastic data of micromorphic deformation. DNS2_H: hardening data of micropolar deformation. The micromorphic_ex4_RVE1.csv presents the unseen stress history data for testing purpose. DNS3_H: hardening data of micromorphic deformation. The micromorphic_ex5_RVE1.csv presents the unseen stress history data for testing purpose. Learning tasks: In each folder, the "data_csv" folder contains all the available sequential stress-strain data in the .csv format and the yield_stress.csv contains the yield stress points sampled from the initial and evolving yield surface. Task 1: In "CamClay_init1_mpol", "CamClay_init2_mpol", and "CamClay_init3_mpol", the task is to reconstruct the initial yield surfaces given "yield_stress.csv". Task 2: In "DNS2_H" and "DNS3_H", the task is to learn from the sequential data in "data_csv" and produce the test sequential data in "micromorphic_ex4_RVE1.csv" and "micromorphic_ex5_RVE1.csv". The inputs (features) of the sequential data are ('eps11','eps22','eps12', 'k31','k32', 'G111', 'G222', 'Gsym121', 'Gsym212') while the outputs (labels) are ('sig11','sig22','sig12','m13','m23', 'zeta111', 'zeta222', 'zetasym121', 'zetasym212')
